Minor pendantry only ...
Your cruise C of G is related to the MAC (Mean Aerodynamic Chord)
Keep in mind that the practical significance of the MAC to the line pilot is nil. The above statement is a bit like saying "a CG of 100.5 inches is related to a scale from zero to 300 inches .." ie, perfectly true but not illuminating.
requires less downward force on the rudder ... the rudder produces less trim drag
Hopefully, you mean tailplane and elevator ?
